Abstract (en)

The present disclosure provides a scanned image correction apparatus (100), method (300) and a mobile scanning device (400). The apparatus (100) includes an image acquisition module (110) disposed on a detector arm (430) of a mobile scanning device (400) and configured to acquire a scanned image of an object under inspection and determine an image parameter of the scanned image during a scanning process of scanning the object under inspection by the mobile scanning device (400); an arm swing detection module (120) disposed at a monitor point on the detector arm (430) and configured to detect a displacement offset of the detector arm (430) in a specified direction and build an arm swing model of the detector arm (430) during the scanning process; and an image parameter correction module (130) configured to determine a change relationship between the image parameter of the scanned image and the displacement offset of the detector arm (430) based on the arm swing model and the image parameter of the scanned image and correct the scanned image based on the change relationship. With the scanned image correction apparatus (100), the imaging quality of the scanned image may be improved and a better correction to the scanned image may be obtained.
